Exes lmoxsox,Xewburgh, N. Y. Filed Au". lb-19H). Serial No. 578,734. To all 107mm it may concern:

Be it known thatI, Exes 'A. Baoxsox, a citizen of the United States, and resident of Newburglnin the county of Orange and State of New York. have invented certain Im u'ovcments in 'Dr 'ing Apparatus, of

This invention relates to certain improvewhich are especially designed and adapted paratns of this general character of a simple of a strong and durable construction, having certain features of novelty aml nuprovemcnt formed in a substantially continuous and exercise of any particular care or attention upon the part of? the attendant, whereby important advantages and increased cfliciency and convenience are attained in the actual use of the apparatus.

The invention consists in certain novelfcatures of the construction, and combinations and arrangenn'nts of the several parts of the improved drying apparatus, whereby certain important advantages are attained and the 'apparatus is rendered simpler, less expensive and otherwise better adapted and more convenient for use, all as will be hereinafter fully setforth.

The novel features of the invention will be, carefully defined in the claims.

In order that. my improvements may be. the better understmd, l will now proceed to describe the same with reference to the accompanying drawings, wherein l have illustrated one embodiment of the invention and in which- Figure 1 is a view in side elevation of an apparatus for drying sand constructed ac.- cording to my invention; Fig. .2 is a frontelevation of the structure shown in Fig. 1; Fla. 2! is a rear elevation of the same; Fig. "l is an enlarged sectional view illustrating certain features of the chute. supporting means which will be la-reinafter referred to; and Fig. 5 is a transverse sectional view drawn to an enlarged scale and illustrating certain features of construction of the heating means.

In these views, 1 and 2 represent spaced A- shaped frame members of'diflcrent relative heights joined or tied one to the other by means of crossed braces or connections 3, these members being "formed of angle bars in the structure herein shown, amt at the BEST AVAILABLE coev tory shaft .5 which ,atl'ords a support for the; drying means as Wlll be hereinafter explained.

In the structure herein shown it will be observed that the different relative heights of the frame members 1 and 3 serve to position the shaft 5 at an inclination for :1 ourpose which will presently beapparcnt. lunch of the bearing members 4 is provided with a depending rib'G having a face contacting with a surface of the corresponding frame member 1 or 2 and such bearing, member is held n place upon suchframe member by If rivets or other suitable fastcnings 7 passed through the ribs (3 and the adjacent frame member.

At- -that side of each member 4 whereat the shaft 5 is upwardly inclined, said shaft is provided with a sleeve 8 fixedly held thereto and the side of each bearing member 4 adjacent to such sleeve 8 is provided with aball race wherein are contained a series ofi balls interposed between such bearing meniber and the corresponding sleeve 8 as shown' in detail in Fig. 4 so as to afford ball bearings which facilitate the rocking or vibratory movement of said shaft. in order to hold the shaft against endwise. movementafter the parts lmve been assembled. a nut or collar 10 is fixed to its lower end portion. in position for contact against the side of the lowermost bearing member -t opposite to the correspondingly positioned sleeve 11, 11 represent alined bo sters supported upon the upper and lower sleeves S. S of central parts in such manner that "a -b bolster has is opposite end Portions extended beyond opposite sids of said shaft. and l2 represents a chute member formed from sheet metal or the like secnred'at. its upper amt lower parts upon the bolsters ll. 11 and cxtemled at. an inclination parallel with aml above the shaft :3 so as to afford a channel along which the sand to be dried ls adapted to be passed. .'\n intermediate. bolster lit is provided for the supportof the central partof the chute member 1'2, being secured tuna sleeve H on shaft- .1 substantially midway between the sleeves S, S. The chute member 12 being thus supported upon the lmlsters which are fixedly secured to sha ft- 5 through the. medium of sleeves S aml l-t, it. will be evident that rocking or vibratory movementof said shaft will be imparted to the chute member to rock or oscillate the. same in a lateral direction. aml for imparting such melting or vibratorv movement to the. parts I have shown the intern'iediatc portion of the chute member provided with bracltets 16 at its opposite sides to which are coupled the upper ends of pitmen 1.7 \\lll(.ll are extended downwardly :nd pivotupper part of each of the said frame mem- I hers I and 2 is secured a bearing memberl t in wluch 13 mounted a rocltable or vibra-t ally secured to the op )ositeends of a walkmg beam, 18 mounted for oscillation upon a shaft 19 and coupled by a link .20 with a cranlc disk 21 mounted upon a shaft 2'.

BEST AVAILABLE COPY end of the chute member 12 and adapted made gradually widened toward its lower part; whcreat. the material to be dried is desurlace over winch said material passes is provided with spaced divergent; ribs 32 iwhich operate to spread the material later- 1 tally and evenly across the width of the chute imeinber so that. the drying operation may j i be the more ell'cctively (ainducted.

Within the chute member 12 aml :uljaeent,

E to the opposite upper and lower ends thcreol" ure trzmsversely extended double manifolds "ll-l and 25 eonntaited with one another by E two series of pipes 26 and 27 extended longitndinally along the inclined bottom of the 'chutc member. .\s herein sil 'Wll. the pipes 27 which alternate bctwccn tlnpi e 2"- and ar of l ss diameter than ai-l pipes 2 are closclv adjacentto thc iIu-iin d bottom oli the cluttc luctnbcr. while said pipes L i are positi ned at. some distance from said boilotn ol' the chute member whereby it. will be seen that a plurality of grooves are produced between said pipes 'J lextended lengthwise of the chute member and serving for the downward conveyance of the material to be dried in close contact with said pip s 26 and 27. The (TOlllltPt'ilOh ol the. pipes .16

and 27 with the manifolds .Z-l and .25 may I be ell'ectcd in any desired manner but it has been found desirable to avoid the use of unions and to screw said pipes directly into the manifolds.

Dischar ing into the nmnil'old 24 at the upper end ot the chute 12 is a steam inlet connection 28 shown on the drawings as a llcxiblc member leading from a suitable source of supply which may with advantage be. the boiler for the operating engine. while the lower manifold 23 is in communication with the similar flexible discharge connection 29 from which condensation llowing downward through the inclined pipes 2t and .27 may be led hack to the boiler of-the engine in a well-known way.

lly the construction and arrangen'ient of the parts as'above described, it will be seen that in the operation of the apparatus, the

: inclined spreader 30 positioned at the upper to receive the sand or other material discharged over the end of the conveyor 31 and to direct the same into the upper end of the t inclined chute member. The spreader 30 is livered to the chute member and its inclined T surface thereof will be fed downward over adrenal to be dried will he coiitiinuously supplied to the upper part; ot the chute member aud being sprcad'over the inclined the grooved heating surface a llorded by the pipes .26 and 27, the circulation of the steam through said pipesscrving etl'ectivcly to dry such material during its descent, while at; the same time the rocking or OSCllltltOl')", movement imparted to the chute member;

by the pitmen 15 being directed laterally with respect to the travel of the material over the inclined drying surface, will opcrate to agitate the material and to assure an even spreading of the material transversely of the width of the chute and assist in feeding the same downward to the lower discharge end of said chute member and thereby n'iaterially increase the ellicieney of the machine for drying.

At opposite. sides of the longittuliuall) j grooved surface ol the chute tnetnbcr alforded bv the pipes 2t and it, said chute 1 rocking or oscillatory movement of the. chute member, I have shown the rod :20 ad nstably secured to the crank dislt ..'l as indicated at 212'. in Fig. I. so that the throw imparted by the crank dislt to the walking beam may be \illittl.

it has been ascertained in the practical 1 use ot' the apparatus c nstructed as above des ribed that a considerable strain 'is c.\' cl'tcd longitudinally ol the machine and in order to resist this strain an inclined brace ii is provided at the .lorward or discharge end of the apparatus, which brace as shown in the drawings formed from spaced bars secured to the upper part of the frame 1 and e.\"tcnded downwardly thcrcl'ront at an outward inclination with their lower ends eontacting with the surface whercon the upparatus is sumiortta'l.

From the above description, it will be seen that. the improved drying apparatus constrncted according to my invention is ol an extremely simple and comparatively inexpensive nature and is particularly -well adapted for use by reason of the facility with which the drying operation is conduetcd and of the general increased capacity for drying and it will also be obvious from the above. description that the apparatus is susceptible ot some change with- 1 member is provided with raised longitu di- .nallv extended side walls 12 which ctlccont material departure from the principles and spirit of the invention and for this r a i son I do not desire to be understood as limiting myself to the precise formation and arrangement of the several parts of the apparatus, herein set forth, in carrying out v my invention in practice.
